Right-o. We've batch converted the images to JPG and are very happy with the
resulting quality so will likely post those instead of the TIFFs because we
want to make absolutely certain they work with the media player and can be
scaled and downloaded at different resolutions. In fact on reflection, the
TIFFs were so huge that we're not even sure they would be that usable for the
average person, they crash the simple image viewers on our own PC's, and if the
only option to view them in the commons is by download (ie they aren't able to
be scaled and downloaded at different res in the viewer) they won't be much use
to the greatest number of folks. We also would love for them to populate
articles if possible so I think JPG is the most practical way to go for this
batch. Though I certainly take Fae's point from last year around not shying
away from a challenge and opportunity to fix something, I'm sure there will be
more opportunities for that with future BL batches!
Thanks everyone for the feedback/convo!

Oddly enough, vips scalar was the problem here. There used to be a bug that
causes that, its been fixed now (for a long time now), but the old version was
cached. If you see any images that are almost entirely white with a bit of
black around the edges, do ?action=purge to the image description page.
However there appears to be a second bug (
https://phabricator.wikimedia.org/T116947 ). Rendering the file in sizes less
then 2523px seems to be broken.

thanks - non-render size up to 50 MP which should get most images in use
but there are still some larger

There shouldn't be (anymore). Do you have any examples of files with that error?
There are a few (I mean few as in probably less than 10 over all of
commons) tiff files that don't render that I am aware of, but they don't have
that error and instead just time out.
